Description
Technical field
The present invention relates to fluorine plastic product field, particularly relate to a kind of withstand voltage, wear-resisting teflon sleeve.
Background technique
At chemical industry, oil, natural-gas transfer pipeline field, because fluoroplastic have excellent water pressure resistance, corrosion-resistant, high temperature resistant, ageing-resistant performance, applies more and more extensive, wherein teflon is the most extensive, and teflon has electrical insulation, can-250 to 260 degrees Celsius of lower long-term works.
But teflon has slickness, do not glue with other metal pipe, so be limited by very large in making sleeve pipe, there is huge difference in the expansion coefficient of teflon and tubing simultaneously.
Although teflon has certain hardness, heavy caliber sleeve pipe uses, and intensity is nowhere near, and for this reason, the invention provides a kind of withstand voltage, wear-resisting teflon sleeve, has good performance, and anticorrosion and intensity can be met.
Summary of the invention
The invention provides a kind of withstand voltage, wear-resisting teflon sleeve, have good gas liquid transmittability, corrosion-resistant, intensity is high.
Described one is withstand voltage, and wear-resisting teflon sleeve, comprising: sleeve body, and sleeve body is pipeline from inside to outside successively, fluoroplastic material layer, encapsulant layer, Steel Support layer, aramid fiber protective coating, surface oil enamelled coating.
Described pipeline is the circulation passage of liquid, gas, and described pipeline area accounts for the over half of whole sleeve pipe area.
Described fluoroplastic material layer adopts fluoroplastic PFA and PPL to be mixed, PFA resin formal name used at school soluble poly tetrafluoroethylene, the fluoroplastic of newer melt-processable, the fusing point of PFA is high, and PFA is heat-resisting, cold-resistant, chemical stability, mechanicalness, insulating properties, self lubricity, folding resistance, resistance to cracking excellent.
PPL, polyparaphenylene phenol is wear-resisting, sealing material ideal in the industries such as metallurgy, chemical industry, and high life is high temperature resistant, due to very large rigidity and regularity, makes it cannot not be molten insoluble, and self machine shaping difficulty, need fill the blended use of other materials.
Described fluoroplastic material layer adopts teflon to add polyparaphenylene phenol, and through Mold Making, dry, high temperature sintering, secondary treatment obtains fluoroplastic material.
Described encapsulant layer fills mica flour and calcium stearate, and mica flour and calcium stearate have good fire performance.
In described encapsulant layer, be also provided with elastic gel, be convenient to delay fluoroplastic material and Steel Support layer because the difference of thermal expansion, and cause the destruction to metallic material.
A kind of optimal technical scheme, also around being provided with one deck fibre reinforced layer outside described elastic gel, improves the voltage endurance capability of sleeve pipe further.
Described Steel Support layer, adopts copper product or aluminum alloy material to make, plays a supporting role to whole teflon sleeve.
Described aramid fiber protective coating, adopts aramid fiber 1313, aramid fiber 1313, and virtue wheel in position between being called, full name poly, structure of molecule is the regular large molecule of sawtooth pattern, can decompose before melting, not burn in flame, have in flame retardant property.
Described surface oil enamelled coating, can prevent sleeve pipe to be oxidized further, improves the working life of sleeve pipe.
A kind of optimal technical scheme, is also provided with phosphor at described surface oil enamelled coating, is convenient to sleeve pipe and constructs in the dark.
Meanwhile, 3 construction grooves, are convenient to the construction of sleeve pipe in described teflon sleeve arranged outside.
The invention has the beneficial effects as follows: one of the present invention is withstand voltage, wear-resisting teflon sleeve, structure is simple, the intensity that existing metal is the same, has again the decay resistance of plastics, has a good application prospect in sleeve pipe field, that conveying is acid, the perfect medium of alkalescence and etchant gas, pipeline flow performance is good simultaneously, long service life.
